Table 17-1. Memory Allocation for Endpoints
When the SIE writes data to a FIFO, the internal data bus is driven by the SIE; not the CPU. This causes a short delay in the
CPU operation. The delay is three clock cycles per byte. For example, an 8-byte data write by the SIE to the FIFO generates a
delay of 2 µs (3 cycles/byte * 83.33 ns/cycle * 8 bytes).
17.3
All USB devices are required to have a control endpoint 0 (EPA0 and EPB0) that is used to initialize and control each USB address.
Endpoint 0 provides access to the device configuration information and allows generic USB status and control accesses. Endpoint
0 is bidirectional to both receive and transmit data. The other endpoints are unidirectional, but selectable by the user as IN or
OUT endpoints.
The endpoint mode registers are cleared during reset. When USB Status And Control Register Bits [6,7] are set to [0,0] or [1,0],
the endpoint zero EPA0 and EPB0 mode registers use the format shown in Figure 17-2.
Bits[3..0]: Mode.
Bit 4: ACK.
Bit 5: Endpoint 0 OUT Received.
Bit 6: Endpoint 0 IN Received.
Bit 7: Endpoint 0 SETUP Received.

In 5-endpoint mode (USB Status And Control Register Bits [7,6] are set to [0,1] or [1,1]), Register 0x42 serves as non-control endpoint 3, and has the format for
non-control endpoints shown in Figure 17-3.
Two USB Addresses:
A (3 Endpoints) and
These sets the mode which control how the control endpoint responds to traffic.
This bit is set whenever the SIE engages in a transaction to the register’s endpoint that completes with an ACK packet.
1 = Token received is an OUT token. 0 = Token received is not an OUT token. This bit is set by the SIE to report the type
of token received by the corresponding device address is an OUT token. The bit must be cleared by firmware as part of
the USB processing.
1 = Token received is an IN token. 0 = Token received is not an IN token. This bit is set by the SIE to report the type of
token received by the corresponding device address is an IN token. The bit must be cleared by firmware as part of the USB
processing.
1 = Token received is a SETUP token. 0 = Token received is not a SETUP token. This bit is set ONLY by the SIE to report
the type of token received by the corresponding device address is a SETUP token. Any write to this bit by the CPU will
clear it (set it to 0). The bit is forced HIGH from the start of the data packet phase of the SETUP transaction until the start
of the ACK packet returned by the SIE. The CPU should not clear this bit during this interval, and subsequently, until the
CPU first does an IORD to this endpoint 0 mode register. The bit must be cleared by firmware as part of the USB
processing.
